The aim of this study was to determine some morphological characters and genetic relations of indeterminate green bean accessions having different seed coat color collected from the Black Sea region of Turkey. In this research, a total of 39 green bean accessions and one kidney bean accession consisting of different main seed coat colors (white, black, yellow, green, brown, red, and dark red) and mixed seed coat colors were used. Plants were produced under greenhouse conditions for morphological characterization. We used 43 morphological characters described by UPOV for indeterminate green bean. In molecular analysis, the sequence-related amplified polymorphism (SRAP) marker system was used. A total of 21 primer combinations produced 138 bands. DNA band profiles were analyzed by NTSYS and a UPGMA dendrogram was generated. The total polymorphism rate was found to be 85.5%. According to research results, indeterminate green bean accessions showed a high level of morphological variation; however, narrow genetic diversity was detected based on molecular analysis.
